DOORi-SILL.

SPECIFICATION forming part of Letters Patent No. 365,774, dated July 5,1887..

Application filed January 29, 1887. Serial No. 225,571. (No model.)

To all whom it `may concern:

Be it known that we, JAoon B. BEAM and GEORGE iV. BEAM, both of Big`Run, Jefferson county, Pennsylvania, have jointly invcnted certain newaud useful Improvements in DoorSills, of which the following is aspecification.

The object of our invention is to provide an improved arrangementwhereby a weathertight joint is afforded at the bottom of the door, andalso to provide a removable doorsill of convenient andeconomicalstructure.

In the accompanying drawings, Figure l is a view of the exterior of thedoor and its frame; Fig. 2, avertical section on the line 2 2 of Fig. l,and Fig. 3 a horizontal section on the line 3 3 of Fig. 2.

A represents an ordinary door-frame, B the sub-sill, and O the sidestrips against which the door closes. The removable sill D is preferablyformed of metal, and is cast or wrought so as to be ofr the archedcrosssectio'n shown in Fig. 2. It slides between the sides ot' thedoor-frame, and is retained in place by sliding bolts d, which shootinto the frame. These bolts are preferably arranged, as shown, in thehollow on the under side of the sill, and are thrust back, and `forth bymeans of studs orv handles l, which project through slotsfin the sill. Alongitudinal depression, preferably havi nga cross-section representedby the quadrant of a circle, (see Fig. 2,) is formed in the upper faceof the sill. A rocking weatherstrip, E, is pivoted by means of shortjournalstuds formed on its ends in the end walls, d', of thelongitudinal depression or recess. At one of these bearing-studs theweather strip E is cut away, as shown, and acoiled spring, F, Visdisposed around it, one en dbeing fastened to the sill and the otherbearing upon the under side of the strip. The normal tendency of thisspring is to throw the Weather-strip' up vertically against the outerface ofthe lower edge of the door, as seen in Fig. l; but this can onlytake place when the door is closed, be-

cause of an extension, x, at one end of the strip, which is of suchlength that the door, even when in its most open position, cannot passoft' from it. The weather-strip is therefore held horizontal and Hushwith the sill when the door is open. XVe preferably form the sill atthis end with an extension, y, which overlaps the door-frame and lies ina recess in the face of the frame, or under the edge of astrip, z, whichmay be secured on the frame. 't

When the door is open, the weather-strip E is horizontal and liesperfectly flush with the Lipper face of the sill; butwhen the door isclosed the strip is automatically thrown up vertically against its face,so as to form a closed joint. With this construction there is noobstruction or irregularity upon the face of the sill, as we dispenseentirely with the ordinary lugs or iingers which have heretofore lbeengenerally used in devices of this class.

Apertures o, leading from the'bottom of the recess in the sill to theoutside of sill, may be provided to draw oft' any water that may find lhas been proposed to form a closed joint bel tween the bottom of a doorand the sill by means of a hinged strip which is pressed up against theunder edge ofthe door by a spring. XVe do not, therefore, claim any suchsubjectsmatter.

Ve are aware of the patents of Moore and Vhitney, No. 155,807; Brown andBrownell,

No. 126,014, and Kintner, No. 313,742, :and do not claim anysubject-matter shown therein; but l What we claim as our invention isl.An arched metallic door-sill provided with retaining-bolts at its endsadapted to shoot into the doorjamb for Aholding the sill Vin place, andhaving a recess inits upper face, in combination with a flatweather-strip pivr oted in the end walls of the recess and adapted tolie horizontally flush with the sill when the door is open and to beturned up intoa vertical position against the side ofthe door whenclosed, substantially as and for the purpose set forth.

2. The combination of a door-sill formed ICO e v p '365,774

with a recess in its upper face, having slots f, a weather-strip pivotedin the end walls of the recess, the retaining-bolts, one in each end ofthe door-sill, whiehare adapted to shoot into the door-jamb, and thestuds orhandles on the bolts, which project through slots in the sillbelow the Weatherstrp, substantially as and for the purpose set forth.

3. The combination of' a door-sill formed with a. longitudinal recess ordepression in its upper face, a. weather-strip pivoted at its ends inthe upper part of the recess and which lies horizontally ilush with thesill when the door is open7 and a spring which throws the weatherstripup into a vertical position parallel with and against the side of thedoor when the door is closed7 substantially as set forth.

4. The combination of a doorsill having a depression in its upper face,a pivoted weatherstrip, the spring which throws the Weather- A 2o stripup against the faee of the lower edge of the door when the door iselosed7 und the eX- tension of the weather-strip,by means of which thestrip is held horizontally flush with thesill when the door is in itsmost open position. 25

In testimony whereof we have hereunto subscribed our names.
